IMPROVEMENT IN LAWN-MOWERS.

Specificat-ion forming pnrt of Letters Patent N0. 100,840, datcd Mm7ch15, 1870.

T0 all whom it mag; concern: v

Be it kuown that I, JOSEPH ARBEITER, of Bast Hartford, countyofHartford, and State of Oonneeticut, have invented certain new and usefulImprovements in Lmvn-Mowers; und to enab1e others skilled in Lhe art t01nake and usethe same, I will proceed to describe its eonstruction undoperation, referring to the dmwings, in which the szune 1et-ters andfigures indieate like partsin each ofthe figures.

In the accompanying dmwings are shown the several parts which when puttogether, make up Eh working maehine, the objeet 0f which is t0 show inthe drawings themselves zus mach as possible the form 2md eonstructionof each distincivepart 01 portion ofthe 11mchine; and the inventioneonsistsin tl1e combination and a-rrangement of the arts that enter int0the construction 0f the operating arts 0f the machine, and theeombination of special parts for speeial purposes.

Figure 1 is a t0p 01 plan view 0f this invention. Figs. 2 and 3 areoutside views 0f the sides 0r frame-work 0f the maehine. Figs. 4 am]. 5are wheels 2u1d stud-plates upon which they am hung and by which they amadj usted t0 secure a proper elevation, :md allow it (the n1achine) soglide easily and freely over the ground. Fig'. 6 am the girts by mem1sof which the sides 01 frame-wo'rk are secured firmly together. Fig. 7 isa fixed 01 stationary straight-edge cutter-blade. Fig. .8, is a spimlly-formed rotating cutter, hzwing the gear by whieh 113 is drivenseeured upon 0ne end of its axis-bearings. Fig. 9 Shows 11110groundroller which snpports the fmme-work, and from the revolutions ofwhiehmotion or a-otion is imp2uted to theworking mechanism 0f themachine. Fig. 10 shows a shaft having a gear seeured upon each eudthereof, f01 transmitfing motion from the ground-roller t0 the revolvingcntter. Fig. 11 is a driving-gear 112W- ing a ratehet formed thereon,and in use is fitted closely und tnrns free1y up011 the shaft 0f theground-roller. Fig. 13 is a flzmge-eolkm, which is fitted and securedfirmly upon fl1e shaft 0f the ground-roller outside 0f and in eloseproximity with the driving-gear h ving a spring-pawl device arranged.therein, which will allow the ground-roller to turn backward Withoutimparting moti on to the meehanism 0f the machine. lhe spring-pawl J canbe so eonstrueted zus t0 be held away from the ratehet K at pleasure, sothat the machine cm1 be run forward or backward with out turning theeutter. Fig. 12 shows the details of the pawl device, which is arrangedin tl1e said flangecollar. This paw1 works in the notches of tl1emcchet, and when tl1e maehine is pushed forward imparts motion t0 thewhole workingmechanism of ol1e machine.

a, in Fig. 13, is aflange-collar, l1aving ahub, b, by means 0f which itis made fast upon the outer end of the shaft G in any common way. Thisflange is also provided With a chamber, c, to reeeive and allow a spimlspring, d, t0 work in and act upon the sprin g-pawl e. (Seen in Fig.12.)

f is a boxing in which the pawl-lever g is arrzm'ged, and operates tohold the pawl 0 out of contaet with the ratchet-teebh k 011 gearwhee1 OThis 1ever g is pivoted in boxingf a1; i, so that when it is thrownback, it (the spring-pawl 0,) will cont-raco spring d, and Wilhbe heldout of contact with ratchet-teeth k 0n:jy gear-wheel O and is held outof contact by means of zu pin, h, inserted through the boxin f, whiehallows rollers H t0 revolve. freely in either direction withoutoperating the mechanism whieh revolves the cutter; aud whenever it isdesirable to operate the eutter, it is only neeessary to remove the pi11h, when the spring-pa'wl e Will engage Wi ththe teeth k 011 gear-wheelC, and'the e1itter will again be made to revolve by pushing the machineforward.

Figs. 14 and 15 are caps which cover the boxing and the mechanismarranged therein, formed 011 t11e sides 01 fmme of the machine. Fig. 16a1e oscillating arms, arranged upou the shaft 0f the ground-roller, undadjusted to their proper position by means 0f bolts 01 screws workingthrough s1its formed. in the side 'frame-work, by mezms of whieh theoperator pushes the machine before hi1n.

The sides 01 frame-work, as shown in Figs. 1 and 2, am design'ed t0 be1nzmde 01' cast metal, hzwing the boxing A B to reeeive, c0ver, andprotect the gears C D E F from bang; clogged or otherwise injured 01rendered inopemoive by exposure. These geimrs 1nay be varied in Size,number 0f teeth, &c., t0 SGOH1'O oho.

desired numbor of revolutions of the revolving c11tter 2111(l tl1e easyworking of tl1e 11121- ol1ine, and tl1e gea.r C may 1121ve itsratohetteetl1 oast o1 formecl thereon.

'Il1e orifioes 1 m1d 2 are macle having proper reference to suitablebearing-surface for the sl121tt G of tl1e roller I-I, es also tl1ose of3 111d 4 for the sh:tft I.

Suitable g11ideways J are also formed 111 tl1e frame-work, 111 whiol1the sliding z1cljustz1ble journal-boxes K 211*e fitted, so es to bemised 2111d lowored, a-s desirable, by means of setsorews L, for thepurpose of adjusting the entting-edge of tl1e revolving outter M inolose proximity witl1 tl1e edge of the stationary autterQ. Thesejournal-boxes K a1e fitted closely to tl1e w:1ys J, 2t1ld so as to beeasily raised or lowered, as desirable, und hold firmly in the desiredposition by means of tl1e set-sorews L. They are also provided witl1bearin gs 5 and 6, to receive the bea.rings of the revolving c11tter M.

I propose, in tl1e manufaoture of these 11121- el1ines, to 21112111g0 21bla.de 11p011 21ml near the outer edges of the outter M, hzwing slitstherei11 fo1 the passage of fastening a.11d adjusting bolts, for tl1epurpose of adjusting and chang- 1'ng them from timo to time, asdesirable, to compensate fo1 Wem, breakage, &o.

N, o:1ps for oovering the boxesAl3, 2111d are secured thereon by sorews,so tha-t they 02111 l1e easily 111d quiokly removed 111d replaoed.

O are tootl1ed o1 raok surfaces formed 011 tl1e frzune-work, havingslots O forn1ed therein for the reeeption and pl21y of fastenin g-l1oltsP, the objeet of whioh is to adjust and finnly seoure r.l1e studs O alsohaving teetl1 or raok-surfztces to fit the surfaoe O, ancl so es to beez1sily adjustecl up o1 dow11 130 tl1e desired plaoe, 2111d hold firn1lyin the clesirecl osition by means of fastening-bolts P. These studs 0a-re provicled with an ax1' s-piu, upon wl1ioh the wheels R are seoured.Tl1e object of these wheels is to hold ehe front portion of tl1e maohinez1t its proper heigl1t fron1 tl1e ground, ancl by being oonstruoted oflarger diameter tl1a.11 ordinary guicle-wheels in lmvn-mowers, 111d so21s to be adjusted :1t any required Position 011 tl1e m11- 0110 end oftl1e 211111s S is plaoed upon the I shaft of tl1e roller H, 111d isfurther secured to tl1e frame-work by sorews o1 bolts working througl1the slots T formed in the frame-work. The outer ends of these handlesare oouneeted by a. oross-bar, U.

I have thus endeavored to show in tl1e drztwings ancl speoification thenature 211111 tl1e 0011- struotion of this invention, so es to enable aperson skilled in tl1e a1t to make und use tl1e Same therefrom.

What I ola-in1, therefore, 111d desire to secure by Letters Patent, is

l. The oombination of tl1e roller H, fianged oollar fast 011 shaft G,'and having spring-pawl provided witl1 tl1e engaging and disengagingmeol1anism desoribed, arranged therein,with tl1e ratohet-teeth ongeztr-wheel C, whioh freely revolves upon sl1aft G, and g'1ves motion tothe revolving outter through intermediato gearwheels, when all the partsare construoted and arrar,;ed to operate in tl1e 11121111101 21ml forthe purpose desoribed.

2. 'll1e roller H on shaft G. having the flange- 0011211 and spring-pawlprovided with tl1e engz1gin g and. disengaging mochanism desoribod, theratohet-teeth 011 wheel C, inolosed gearwheels O D E F. and intermediatesl1aft, revolving a-dj ustable outter M, transverse outter Q, adjustablewheels R, and adjustable arms S, all construotecl a.nd arrangecl Withrelation to eaol1 other and. to the f1ame of tl1e machine, a-s hereindesoribed.
